GAS-GOVERNO R.

SPECIFICATION forming part of `Letters Patent No; 283,25, dated August 14, 1883.

Application mea May 31, 1883. (No model.) p

and WALTER E. HOPPER, both citizens of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Gas-Governors, of which the following is a i specification.

The obj ect of our invention is to prevent the disturbanceof the flames of gas-burners which are suppliedv with gas from the same servicepipe which furnishes gas for gasengines, and this object we attain in the manner which we will now proceed to describe, reference being hadto the accompanying drawings, in which- Figure l is a vertical section of the regulator by which our invention is carried into effect; Fig. 2,"a plan'view; Figs. 8 and 4, sections drawn to an enlarged scale, and showing the upper ends of two pipes appertaining to the regulator; and Fig. 5, a view illustratin a modification of our invention. 2 i

Where a gas-engineis furnished fromthe same service-pipe which suppliesgas-burners i for illuminating purposes, the flames of the said burners are always disturbed, owing to the demand of the engine for sudden intermittent supplies of gas. In order to obviate this difficulty we interrupt thel continuity ofthe servicei )e b a regulator which we will now` proceed todescribe. l i

A represents fthe terminal portion of the servcepipe from which the burners derive their gas, and B the delivery-pipe, for cou-' I veying gasto the gas-engine only.

A tank, D, preferably of cylindrical form and closed at the bottom, contains a supply of water extending to about the line x, and in this water is immersedthe lower portion of the holder G, which consists of an open-bottomed cylinder suitably guided in the tank, and which will be particularly alluded to hereinafter. i

The terminus of the servce-pipeA communicates, preferably through a chamber, NV, formed in the bottom of the tank, with a vertical pipe, A, which terminates within the holder above the water-line x. y i i On the top of the 'pipe A/is a seat for the valve H, the spindles of which are guided by valve may be adopted. To the top of the pipe cap I.

A', and inclosing the valve, is secured a cap, I, having an opening, i, of `much less area than that of the valve-seat. As long as the gas in the holder is at the same pressure as that in the main the valve remains closed by its own weight; but when the pressure of gas in the holder is reduced the valve will open and the equality of pressure of thegas in the holder and main will be restored.

valve is notV simultaneous with the removal of gas from the holder, there being a slight hesitancy or sluggish action of the valve before it opens, owing partly to its `weight and partly.

to thev comparatively small opening i in the A gas-engine demands intermittent and such briefly-continued supplies of gasthat the latter may be said to pass to the engine with sudden pulsations. i Vhen a pulsation occurs, however, it doesnot disturb the valve, owing to its hesitancy in op ening, and hence the pulsations have no effect on the gas in the servicepipe A-or` on the dames of 4the burners, the opening of thevalv'e and the restoration of an equality of pressure of the gas in the main and in the holder occurring during the intervals between the pulsations.

The holder is so constructed that in the ab- It. should be here, understood, however, that this opening of the sence ofthe pressure of gas it will rest lightly Y sorting to any addition" or removal of weights or any other adjustment.

lt is not essential that the valve should be y atthe top of the vertical pipe Ai, or within thelimits of the holder or tank. For instance, there may be a valve-chest, K, at `the point shown in Fig. 5, for containing a valve to perform the same duty as the valve H; but we prefer. the plan of placingthe valve at the `upvper end of the pipe A. p

A glass tube, y, communicates with the tank, for indicating the height of watertherein. W'e claim as our invention# IOO l. The mode herein described of preventing the demands of a gas-engine for intermittent supplies or pulsations of gas from disturbing the flames of gas-burners, the said inode oonsisting in causing the termination of that portion of a service-pipe which supplies the burners to admit the gas to a holder during` the intervals between the pulsating` eseapes of the gas therefrom to the engine, and excluding the gas from the said holder when the pulsations occur, all substantially as set forth.

2. The combination of a gashOlder, the terminal portion A A of a service-pipe, provided with a valve opened by the pressure of gas when the latter enters the holder, and a delivery-pipe, B, for directing gas to the gas-engine from the said holder, substantially as set forth.

, 3. The combination of the holder,v the inletpipe with a valve, H, and a cap having an opening less in area than the Valve, With the 2o outlet-pipe B, substantially as specified.

4. The combination of the tank D and the holder G, automatically and constantly bal- .anced in the said tank under different pressures of gas, With the Valved inlet-pipe and the 25 outlet-pipe, substantially as described.

In testimony whereof We have signed our names to this speoiieation in the presence of two subscribing Witnesses.
